Howdy. Most likely satellite SirusXM Radio was a standard feature of your radio and free for a period of time. I left a short feedback of my issue here https://sirius-xm-radio.pissedconsumer.com/review.html . I think with each new day of listening to SirusXM Radio you are convinced that you need to keep this service. Or, if you've just bought a used car with SirusXM Radio features built into your audio system, you're wondering if it's worth paying for.
